Abstract

The utility model relates to a tyre used for operation under overload conditions, which comprises a tyre body, wherein an under-shoulder part of a tyre shoulder area on the outer side of the tyre body is connected with a sidewall area in a concave manner, thereby ensuring that a maximum deformation position of the tyre is transferred from a maximum width position of the tyre upwards to an under-shoulder concave position. The under-shoulder part on the outside of the tyre body is connected with the sidewall area in a concave manner rather than in the original linear tangency manner, so that the contact and extrusion between the sidewall parts of twin tyres in a heavy load state are effectively avoided, and the tyre burst of the twin tyres is reduced.

Description

Tire

Technical field

The utility model relates to a kind of tire, especially relates to the tire that operation is used under a kind of overweight loading condiction.

Background technology

The more existing tire that under overweight loading condiction, uses; The front of using like port operation is hung and the tire of Forklift, the expanded letter dumping car tire that mine operation uses etc.; For how the weight capacity that strengthens vehicle can adopt dual installation; As the front hang, the front-wheel of Forklift, the trailing wheel of expanded letter dumping car.Under the heavy load state, squeegee action is very big, and two tire sidewall portions contact extruding easily, rubs during operation, thereby causes the phenomenon of blowing out, and has a strong impact on the safety in utilization of tire, has shortened the service life of tire.

Summary of the invention

In order to overcome the above-mentioned shortcoming of prior art; The utility model provides a kind of tire of position, sidewall contact can prevent dual installation the time; The contact of position, sidewall can also effectively alleviate tire weight in the time of not only can preventing dual installation, plays certain thermolysis simultaneously.

The technical scheme of the utility model is: tire comprises: tire body, the position is connected with the spill that is connected between the district of sidewall under the shoulder of the shoulder area in the said tire body outside, tire maximum distortion position is upwards moved to by tire the widest part take on the lower recess place.

In order better to solve the problems of the technologies described above, the turn up height of the anti-package bandage of carcass is increased, help to strengthen lower sidewall position intensity, make and move on the tire maximum distortion position.

The beneficial effect of the utility model is: being connected by the tangent connection of original straight line between position and the sidewall district changes the spill connection under the shoulder in the tire body outside; Effectively prevented twin wheel sidewall portion contact extruding under the heavy load state, the generation of the phenomenon of blowing out when having reduced dual installation.And because this position sizing material attenuation can alleviate tire weight, reduce production costs, also have good thermolysis simultaneously, help to reduce the empty generation of tire heat shoulder.

Description of drawings

Fig. 1 is the prior art constructions scheme drawing;

Fig. 2 is the utility model tire front view;

Fig. 3 is the structural representation of the utility model tire;

Among the figure: 1, the tangent connection of straight line, 2, spill connects, 3, the sidewall district, 4, shoulder area, 5, the section horizontal shaft, 6, the anti-package bandage.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

Tire comprises: tire body, the position is connected with the spill that is connected between the sidewall district 3 under the shoulder of the shoulder area 4 in the said tire body outside, tire maximum distortion position is upwards moved to by tire the widest part take on the lower recess place.

Being connected between position under the shoulder in the said tire body outside and sidewall district changes spill into by the tangent connection 1 of original straight line and connects 2, tire maximum distortion position upwards moved to by tire the widest part take on the lower recess place.Spill connection 2, sidewall district 3, the position relation of shoulder area 4 and anti-package bandage 6 is as shown in Figure 3, and tire deforms under the heavy burden state; Distortion concentrates near the sidewall district 3 the section horizontal shaft 5 generally speaking, after changing spill into and connect 2 by the utility model, deforming zone will on move to spill and connect the zone shown in 2; Tire will can not deform at its section the widest part; Thereby position, dual installation sidewall contacts and the phenomenon of blowing out of initiation when effectively having avoided heavy load, and because this position sizing material attenuation, tire weight is able to alleviate; Can reduce production costs, also have better heat radiating effect simultaneously.The turn up height of anti-package bandage 6 more generally designs to be increased, and helps to strengthen lower sidewall position intensity, makes to move on the tire maximum distortion position to spill to connect the zone shown in 2.

Claims

1. tire comprises: tire body is characterized in that the position is connected with the spill that is connected between the district of sidewall under the shoulder in the said tire body outside.
